Modern network applications are often built on fiber optics, twisted pair cables and other demanding applications to provide power and wireless communications. Due to their superior performance, Power Over Ethernet (PoE) Controllers has become a reliable and competitive solution in this market. TPS23754PWP is an integrated Power Over Ethernet (PoE) Controllers from Texas Instruments which helps to simplify the implementation of Power Over Ethernet (PoE) systems. In this article, we will take a look at the application field of TPS23754PWP and the operating principle.

Application Field of TPS23754PWP

The TPS23754PWP is best suited for applications requiring up to 30 W of power. It is suitable for use in IEEE 802.3at/af compliant powered devices, such as VoIP phones, IP cameras, door locks, and Wi-Fi access points. It also supports the proprietary Cisco pre-standard and HP Auto-MDIX (standard twisted-pair cable) modes of operation. In addition, the integrated device can detect and limit excessive inrush current and provides over temperature and over current protection. Furthermore, the integrated device provides up to 60V input protection with automatic reset, hot-swap protection, and line fault protection.

Working Principle of TPS23754PWP

The TPS23754PWP is powered by a 5V to 60V input voltage and integrates the power supply, control circuitry and providing additional features for an overall Power Over Ethernet (PoE) system. The TPS23754PWP works in both IEEE 802.3at/af compliant and proprietary pre-standard modes. When the system is in an IEEE 802.3at/af compliant mode, the device supplies power from a 48V PoE source to the powered device, senses the current draw and determines if the powered device is compliant or not. If the powered device is not compliant, it will limit the power to 15 W or less depending on the settings.

When the system is in a pre-standard mode, the TPS23754PWP supplies up to 40W of power to the powered device, senses the current draw, and limits the current as necessary. In addition, the integrated circuit provides line fault protection, protecting the powered device from damage due to voltage drops, as well as over temperature and over current protection. Furthermore, it helps to limit the inrush current to the system.

The TPS23754PWP also supports Cisco pre-standard and HP Auto-MDIX (standard twisted-pair cable) modes of operation. In these modes, the device monitors the cable length, detects and limits the inrush current, and supports hot-swap protection with automatic reset. In addition, the device is compliant with the IEEE 802.3at/af standard, allowing the system to be used in different environments.

That\'s it! We have now covered the application field and working principle of the TPS23754PWP Power Over Ethernet (PoE) Controllers. It is a versatile and user friendly device which helps to simplify the implementation of Power Over Ethernet (PoE) systems. It also provides flexibility and scalability in terms of power requirement, line fault protection, and other features. As it is compliant with the IEEE 802.3at/af standard, it can be used in a variety of environments.
